___________ selectively stimulates a₂ receptors in brain neurons thereby suppressing sympathoadrenal activation and lowering blood pressure. A)Clonidine B)Atropine C)Acetylcholine D)Bradykinin

Question

Quizplus · Accepted Answer

Clonidine selectively stimulates alpha2 adrenergic receptors in the brain, leading to a reduction in sympathetic nervous system activity and subsequently lowering blood pressure. Atropine is an anticholinergic drug that blocks the action of acetylcholine, bradykinin is a peptide hormone that causes vasodilation and increased vascular permeability. While acetylcholine may lower blood pressure through other mechanisms, it does not selectively stimulate alpha2 adrenergic receptors in the brain.
